Splitting A Dynamic Disk Group
The dynamic disk group split operation involves splitting the contents of
an imported dynamic disk group and creating a new dynamic disk group
(the Target dynamic disk group) with the objects defined in the dialog
box. This operation is performed on VxVM objects such as disks or
top-level volumes, and includes all component objects such as
sub-volumes, plexes and subdisks.
To perform a dynamic disk group split operation:
Step 1. Select the dynamic disk group to be split.
Step 2. Select Actions > Split Dynamic Disk Groups.
Step 3. Complete the Split Dynamic Disk Group Dialog Box as follows:
Disk Group Name: Enter the name of the dynamic disk group from
which objects are to be split.
Target Disk Group
Name:
Enter the name of the target dynamic disk
group which will consist of the objects to be
split.
Select Objects to
move:
• To select volumes to move, click the
checkbox Split dynamic disk group by
volume, and choose from the displayed list.
• To select disks to move, click the checkbox
Split dynamic disk group by disk,
and choose from the displayed list.
Expand: Click Expand to specify that the objects to be
split should include all other disks that contain
subdisks that are associated with the specified
objects or with objects that they contain. For
example, if you specify that disk01 should be
split off and disk01 contains vol1 which is also
located on disk02, then by using the Expand
button, you ensure that disk02 will also be split
off.
